Abstract The growing demand for renewable energy is driving innovations in solar technology for both outdoor and indoor applications. However, higher efficiency, improved stability, and cost-effectiveness are the highest priorities for the commercialization of solar cells. Recently, tandem solar cells (T-SCs) have emerged as a promising solution to surpass the efficiency limits of traditional single-junction cells. By integrating materials like perovskite and copper–indium–gallium–selenide (CIGS), T-SCs capture a broader spectrum of sunlight, improving power conversion efficiency. Perovskite’s wide bandgap (∼1.6 eV) absorbs high-energy photons, while CIGS’s narrower bandgap (∼1.1 eV) optimizes lower-energy photon absorption. This review examines recent developments in perovskite/CIGS T-SCs, highlighting the complementary properties of these materials and their impact on photocurrent generation. It also compares two-terminal (2-T) and four-terminal (4-T) configurations, achieving efficiencies of 24.6 and 30.1%, respectively. Additionally, the economic potential of perovskite/CIGS T-SCs is explored, focusing on their role in reducing energy costs and enhancing sustainability. Key challenges and future directions are also discussed to advance renewable energy systems.
